One of Birmingham's most-visited attractions is celebrating its 15th anniversary.

Millennium Point opened in autumn 2001 after being developed as a partnership project between Birmingham City Council, University of Central England (now Birmingham City University) and Birmingham Chamber of Commerce.

Since then, it has grown into a popular destination for education and events and more recently became the back drop to the award-winning Eastside City Park which saw a car park turned into a destination in its own right.
